1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The retinal phenotype of Alzheimer's disease (AD), its connection to spatial memory, and the influence of sex on the phenotype are poorly understood. Here, we investigate the retina and spatial memory of 5xFAD mouse models of AD by measuring retinal and behavioral parameters. A custom-built optical coherence tomography (OCT) system is used to image the retina of 32 transgenic and 32 non-transgenic 5xFAD mice over the course of 6 months (3-9 months of age). The Morris water maze (MWM) test was performed to examine correlations between the retinal and spatial memory phenotype of the mouse model. Total retinal and inner retinal layer thickness increased slightly over the measurement period, while outer retinal layer and retinal nerve fiber layer thickness showed no significant change. The correlation analysis between MWM and layer thickness data revealed a positive correlation between inner nuclear layer thickness and spatial memory capabilities. OCT and MWM data revealed sex-based differences in the retinal phenotype of the 5xFAD mouse model, with changes in retinal thickness in different stages of the study and dissimilar correlations between retinal and spatial memory phenotype.
